To all whom z't may concern.'

Be it known that I, RoLANDrs A. BLAIR, a citizen of/the United States, residing at Fort Wayne, in the county of Allen and State of indiana, have invented certain new and useful improvements in Rail Anchors, of which the following is a specification.

My inventlon relates to a rail anchor or antl-creeper, and a primary object of the invention is to provide a novel device of this type which will be light, strong, compact, economical to manufacture and so constructed as to have a great holding power as against the tendency of the rail to creep.

A further object is to provide a 1rail anchor of novel construction which can be used on rails of dierent sizes and having rail bases of dierent configuration.

A further object is to provide a rail anchor which, in addition to the characteristics referred to above, will take a positive hold on the rail, that is to say, is not dependent upon the creeping stress of the rail to hold the anchor in. its rail gripping posi` tion so that, if the device is provided with an abutment, it will hold the vrail against longitudinal movement in either direction.

A further object is to so construct the rail anchor that it may be removed and replaced repeatedly without impairing its holding power. The invention consists of the new and improved constructions, arrangements and devices to be hereinafter described and claimed for carryin out the above stated objects and such ot er incidental objects as will be referred to in the accompanying description.

rlhe invention is illustrated, in a preferred embodiment in the accompanying drawing wherein Fig. 1 is a plan view of a railroad rail showing a rail anchor constructed in accordance with my invention applied thereto.

Fig. 2 is a sectional view taken on line 2 2 of Fig. 1. f

Fig. 3 is a fragmentary view in perspective, of the yoke member of the anchor, and

' Figf-l is a View in perspective of the key member employed in connection with the yoke member.

Like characters of reference designate like parts in the several gures of the drawmg.

llteferring to the drawing, 10 designates a ra1lroad rail and 11 one of the cross ties supporting the rail. lhe rail anchor is preferably of the two piece type, consisting of a rail base embracing yoke member 12 and a key 13 adapted to be driven between the yoke member and the bottom surface of the rail base. rllhe yoke member 12 is made, preferably, of a relatively high carbon steel so as to be resilient. It may be formed by cutting and bending a piece or blank of sheet metal. The yoke member consists of a bar 14 to extend under the base 15 of rail 10, a foot or tie abutting flange 16 and hooks" or jaw forming portions 17 and 18 made by bending over the ends of the bar 14. rThe lip of jaw 18 is longer than that of jaw 17. rlFhe jaws are formed with openings 19 and 20 for the key 13 which, as shown in Figs. 1 and'2, is driven through openings 19 and 20, between the bottom of the rail base 15 and the bar 14 of the yoke member. rlhe openings 19 and 20 are preferably arranged in staggered relation with each other so that the key 13 stands obliquely to the rail. rllhe purpose of this is to check the tendency of the yoke to rock on the key and to provide a convenient arrangement whereby the key may be driven home without encountering the diculties which would otherwise be presented if the large end of the key 13 were in closer proximity to the tie l1.

The jaws 17 and 18 are preferably formed so that they are bent. when the key 13 1s driven home. rllhe dotted lines in Fig. 2 indicate, approximately, the original contours of the jaw, the full lines showing the strained contour thereof when the yoke is under the wedging pressure of the key.

The key 13 is preferably wedge shaped and is bowed in the direction of its length .so that it will be distorted when it is driven home between the rail base and the bar 14 of the yoke. rfhe key is preferably made of relatively high carbon steel so that when 1t is in its applied position it will function as a spring to resist any tendency that the v ibration of the rail may have to move it 1n the direction from which it kwas driven or otherwise loosen its lwedging position between the rail base and the anchor.v

It will be seen that the holding power of a rail anchor constructed as above described will be very reat in proportion to its size and weight. he device has a resilient engagement with the rail so that its hold thereon is not easily affected by vibration or other disturbing influences. The key has a very gradual taper and i's stressed when in its applied position, therefore, having but little tendency to back out of the position to which it is driven. The lips of jaws 17, 18

y are strained when the wedge is driven home.A

The device is easily applied to a rail by irst hooking the jaw 18 over the rail base, raising the yoke and moving it in the direction of its length (to the left of Fig. 2) until jaw 17 is engaged with the other edge of the rail base, then driving the key 13 into position between the underl surface of the rail base and the yoke member. The device is as easily removed from the rail by driving the ykey from its small end. The anchor ma be used repeatedly without detrimental al'ecting its holding power. The same anclior may be used on rails of different sizes and somewhat dilferent cross sectional conligurations. For rails beyond the limits of adjustment of any given key the device may be adapted without change in the yoke merely using a wider or narrower key.

b rIlhe yoke stands at some distance below the bottom of the rail base, particularly at the right hand end (Fig. 2) so that the tie abutting flange 16 does not have to be very long in order to obtain a firm bearing on thel tie even when the latter is of the hewn type. Assuming an abutment for the flange 16 on both sides thereof, for example, when the abutment is embedded in the ballast of the roadbed, the anchor will prevent the rail creeping in either direction.
